PASSENGER CAR EQUIVALENT OF BUSES WITH DIFFERENT NUMBERS OF SEATS

The passenger car equivalent (PCE) of buses in urban areas can be expressed in terms of their number of seats. Buses can affect the road capacity because of the space they occupy and the stops they make restrict the movement of other vehicles. It is shown that there is a strong linear relationship between the number of seats and the PCE value. However, as the number of times a bus has to stop, as well as the time it spends at a bus stop depends upon the average number of people on board, the occupancy factor also affects the PCE of a bus. For a given occupancy factor, there is shown to be a linear relationship between the number of seats and the PCE of a bus. Similarly, for a bus with a given number of seats, the PCE value depends upon the average occupancy, particularly where more bus stops are located close to junctions. Graphs are plotted for various types of single and double-decker central London buses, with one or two doorways to show the effect of occupancy and the number of seats. PCE values vary between 1.0 for a 40 per cent occupied 10 seater bus to over 3.0 for a 100 seater, 80 per cent occupied double-decker with two doorways. (TRRL)
